Cosmological Magnetogenesis From Extra-dimensional Gauss Bonnet Gravity
Kumar Atmjeet, Isha Pahwa, T. R. Seshadri +1
Generation of primordial magnetic fields during inflation typically requires the breaking of conformal invariance of the Electromagnetic action. In this paper this has been achieve…
Primordial Magnetic Field Limits from CMB Trispectrum - Scalar Modes and Planck Constraints
Pranjal Trivedi, Kandaswamy Subramanian, T. R. Seshadri
Cosmic magnetic fields are observed to be coherent on large scales and could have a primordial origin. Non-Gaussian signals in the cosmic microwave background (CMB) are generated b…
Inflation in Higher Dimensional Gauss-Bonnet Cosmology
Isha Pahwa, Debajyoti Choudhury, T. R. Seshadri
A Gauss-Bonnet term naturally appears in the action for gravity when one considers the existence of space time with dimensions more than 1+3. A variety of inflationary models can b…
